Self-drilling steel draining pipe
SIDRA SYSTEM Tecsoil

SIDRA drain (Patent no. PC2005A000015) has been designed with the purpose to install in the ground self-drilling draining steel pipes without the aid of casings that are commonly used to carry out drilling holes in loose grounds, in order to install the common PVC draining pipes.

During the years, SIDRA drain was subject to substantial evolutions and technical improvements until the one currently on the market that is mainly constituted of:

1. High quality steel pipe characterised by the presence of draining holes of about 16 mm in diameter, protected by special “micro-filtering valves”.
2. Metal and/or plastic micro-filtering valves.
3. Protection of micro-filtering valves during the perforation phase, by filling them with a water soluble and biodegradable plastic material.
4. Eventual sacrifical bit with non return valve (if installed with rotary technique).
5. Eventual preventer, in case of drilling below the water table.

SIDRA drains can be supplied in elements of variable length, according to the specific needs of the job site.
The technical evolution of the product brought to consider the SIDRA draining pipe during the drilling phase, as a common drill rod because the “micro-filtering valves”, protected with water soluble plastic material, are effectively locked into the same pipe. This allows the drilling fluids to flow to the sacrificial bit (with pressures up to 15 Bar) without any need for a specific co-axial piping.
